SEOUL, South Korea's foreign ministry urged North Korea Tuesday to make a "wise" judgment amid continued reports of Pyongyang's possible preparations for a missile or satellite launch.

"There are concerns about reports on the situation about the Dongchang-ri," ministry spokesman Kim In-chul told a press briefing, referring to the North's west coast rocket launch site it has reportedly been rebuilding after partially dismantling it last year.

"(The Seoul government) hopes that the North will make a choice, which will be helpful for all, through a wise judgment," he added.

The spokesman also said that South Korea, along with the United States, has been thoroughly monitoring the North's movements at Dongchang-ri since before last month's unfruitful summit between U.S. President Donald Trump and North Korean leader Kim Jong-un in Hanoi.

A flurry of media reports and U.S. think tank analyses of commercial satellite imagery indicated that Pyongyang has been taking steps to reassemble its long-range rocket launch facility.

Some experts said that the apparent rebuilding activity may be part of the North's negotiation tactic to get the upper hand in future nuclear negotiations with the U.S.

The latest Trump-Kim summit ended without a deal as the two sides failed to bridge their differences over the scope of Pyongyang's denuclearization and Washington's sanctions relief.
